This “export filter” plugin for Lightroom allows you to
apply a device-specific crop to an image during output, so that images
fully fill the screen when viewed on the device.
I use it to prepare images
for my iPad and iPhone, but it can be used with any device in mind such as
digital picture frames, tablet computers, TVs, smartphones, etc.
This plugin works in Lightroom 5 (and older versions as far back as
Lightroom 3, though some features depend on the
version of Lightroom).
The same download works for both Windows and Mac. See the box to the upper right for the download link (in orange) and installation instructions.
How To Use
For explicit details on how to use the plugin, see my companion post:
“My Lightroom-to-iPad Workflow: Now a Lot More Refined”
Independent JPEG Group Software
This plugin software is based in part on the work of
the Independent JPEG Group.
The crop, if performed, is lossless (it does not lower the quality of the image) because
it uses the Independent JPEG Group's most-excellent jpegtran software to do the crop.
This plugin is distributed as “donationware”. I have chosen
to make it available for free — everyone can use it forever, without
cost of any kind — but unless registered, its functionality is
somewhat reduced after six weeks.
Registration is done via PayPal, and if you choose to register, it costs
the minimum 1-cent PayPal fee; any amount you'd like to add beyond PayPal's
sliding fees as a gift to me is completely optional, and completely
Note: a Lightroom major upgrade, such as
from Lr4 to Lr5, de-registers the plugin in the upgraded version, so if you
want to maintain registration, a new ($0.01 if you like) registration code
is needed in the upgraded version. It makes for a hassle every couple of
years, I know. Sorry. See this
note for details.

In the POODLE-vunerability dialog, display a raw URL of a page on my site that discusses the issue, so that folks can be independently sure that the dialog is indeed from me and not malware.
Dialog could get cut off on very small screens
Windows Only: Add a one-time check for the POODLE security vulnerability, and alert the user if it exists.
Added iPhone 6, 6+, and a bunch of other devices
Fixed an issue with Creative-Cloud revalidation.
Lr5.5 and later Creative-Cloud installs can now revalidate themselves if needed.
Sigh, had a bug in the Creative-Cloud support.
Now supports Lr5.5+ Creative-Cloud Installs.
Sigh, introduced an error for some folks with the rebuild the other day.
Fixed a bug in the "smoother revalidation" stuff recently added.
Make the revalidation process smoother, especially for folks using Lr5.4 and later.
Added a bunch of stuff to the device database, including new Apple iPads announced today.
Fixed a bug with the aspect-ratio reporting in the keyword-set dialog.
Now works with keywords even if they're not at the root of your keyword tree, so you can freely move the keywords to one subgroup (e.g. "Crops")
and things still work smoothly. This creates some ambiguity if you have the same keyword in multiple locations, so don't do that.
Added some Samsung digital picture frames, Microsoft Surface tables, and some Samsung Galaxy models.
Fix an "attempt to perform arithmetic on field" error.
Update to handle the Mac App Store version of Lightroom.
Tweak for Lr4.1RC2.
The crop-preview tool (OSX only) color selection stuff had stopped working... fixed it, and gave that whole area some extra UI love.
Some keyword interaction in the crop-preview tool wasn't working in all cases.
Enhanced the send-log dialog to hopefully make reports more meaningful to me, yielding, I hope, the ability to respond more
sensibly to more reports.
Fixed an issue with aspect-ratio recognition.
Added data for new iPad and Galaxy Tab 10.1
Update to the debug logging to better track down timing issues that might arise.
Added a new "Standard for Galaxy Tab 10.1" keyword set.
Fixed some bugs related to aspect-ratio matching in the dialog.
Removed kludgy date-based random sort. Some updates for Lr4.
Added crop keyword sets, and a set editor.
For OSX only, added a crop-preview keyword-application dialog. It was a stupendous amount of work, but is very cool!
See "Preview Crop" in the Plugin-Extras dialog.
More on the march toward Lr4, including upheaval in the code to handle Lightroom APIs being discontinued in Lr4.
Update for Lr4 beta: explain in the plugin manager that the plugin can't be registered in the beta.
Had issues with the registration button sometimes not showing.
